GIGI Levangie Grazer, whose producer husband, Brian Grazer, was caught in the latest flap at the L.A. Times, drew stares at media-centric Michael’s as she walked past Matt Blank, Brad Grey, Ben Silverman and Tom Brokaw. Gigi was bubbling about “The Starter Wife,” based on her 2005 novel and starring Debra Messing, which airs May 31 on USA Network. It’s the tale of a 41-year-old mother who discovers her Hollywood studio-boss husband is cheating on her. First clue? He starts wearing an earring.
